A method of coating a thermoplastic substrate, comprising applying a solution-type coating composition to a substrate and curing the coating composition at room temperature to 125 ° C. to form a uniform and smooth film on the substrate, comprising: The coating composition comprises about 45-80% by weight of a film-forming binder and 20-55% by weight of an organic liquid carrier, wherein the binder comprises (A) 40-90% by weight, based on the weight of the binder, of an acrylic polyol, a polyester. A polymer selected from a polyol, a polyether polyol or a polyurethane polyol, and (B) an organic polyisocyanate crosslinking agent in an amount of 10 to 60% by mass based on the mass of the binder, and further comprising an organic liquid carrier used in the coating composition, Based on the mass of the organic liquid carrier used in the composition Process comprising at least 50 wt% tert-butyl acetate. It is also possible to use the method of the invention for applying lacquers, i.e. coating compositions which do not contain a crosslinking agent such as polyisocyanate. |
